Experimental Study on Enhancement of Steel Mechanical Properties by High Pressure Jet Quenching
Keyword(s):
The purpose of this study is to enhance the strength of steel by increasing the percentage of martensite microstructure with a high pressure water jet quenching. JIS SS400 carbon steel was chosen as a test sample. The cooling rate of surface and center reached approximately 180oC/sec and 65oC/sec, respectively. After this quenching process, the metallographic analysis showed that the steel turned into martensite structure. Furthermore, the tensile strength of sample increased from 363MPa to 543MPa; the yielding strength increased from 284MPa to 420Mpa. In general, the overall enhancement of mechanical strength was about 140%.
